BACKGROUND OF THE INVENTION This invention relates generally to thefield of photographic storage magazines. To supply the type of projectordescribed in the above-identified applications a storage magazine whichwould present the slides to the transport apparatus was necessary.Additionally, it was imperative to provide a magazine which presentedthe slides to a transport mechanism accurately and with precision.Furthermore a magazine which required proper orientation to be insertedinto the projector was desired.

Since prior slide projectors have in general required entry of theslides in a vertical attitude, extensive treatment of the problemsherein obviated has not appeared in the prior art.

SUMMARY OF THE INVENTION The slide magazine to be described hereinpresents the stored slides to the slide projector in a horizontal plane.Furthermore this slide magazine has features which assure its accuratepositioning relative to the slide projector and the accurate positioningof the slides relative to the transport mechanism of the slideprojector.

BRIEF DESCRIPTION OF THE DRAWING The features of the invention willbecome more apparent in the following description of a preferredembodiment and the drawings in which:

FIG. I is a perspective of the slide magazine.

FIG. 2 is a perspective of the magazine receiving portion of a slideprojector.

FIG. 3 is a cross-sectional view of the magazine in operating relationwith a slide projector.

FIG. 4 is a top view of the magazine in its initial position in a slideprojector.

FIG. 5 is a cross-sectional view of a portion of the magazine inoperational relationship with a slide projector.

FIG. 6 is an exploded view of a portion of FIG. 1 in which for purposesof clarity the cover has been rotated 180 from its normal assembledposition.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1, the novelslide magazine 10 is seen in open condition and upside down orientation.Four upstanding sidewalls 3611,3617, 36c, 36d, each of which is joinedat its edge to an adjacent sidewall, and a bottom wall 38 joined to thesidewalls 36a, 36b, 36c, 36d define a slide storage chamber indicatedgenerally at 14. As depicted, the storage chamber 14 is substantiallycubic; the sidewalls 36a, 36b, 36c, 36d and the bottom wall 38 beingsubstantially square with adjacent sidewalls normal to one another andthe plane of the bottom wall 38 normal to the planes of the sidewalls36a, 36b, 36c, 36d.

Although the sidewalls and bottom may be made of many materials, anadded dimension of utility prevails when the construction material istransparent. Transparency allows an operation to visually determine thenumber of slides remaining and also their character if suitablemarkings, such as color, are added to the stored slides.

The shape of the bottom wall 38 depends on the shape of the slide to becontained in the chamber 14 and could easily be altered to accommodateother than square shaped slides. The shape of the sidewalls 36a, 36b,36c, 36d is determined by the desired slide capacity of the chamber 14which could be increased or decreased by changing the sidewalls 36a,36b, 36c, 36d to an appropriate rectangular configuration.

Two flanges l8 protrude substantially perpendicularly from two parallelsidewalls 36b, 36d and extend along their upper edges from theirjunction with sidewall 360 to a point near their junction with sidewall36a. As best seen in FIG. 6 an irregularly shaped post 8 projectsnormally from sidewall 36d substantially adjacent to the junction ofsidewall 36d and sidewall 3641. Likewise, another identical post (notshown) extends from sidewall 36b substantially at its junction withsidewall 36a.

Two keying projections 30 extend from sidewall 36c beyond the plane ofthe upper surface of the flanges 18 on sidewalls 36b and 360'. A pair ofinclined plane embossments 46 (FIG. 3) gradually increasing from thebottom of the chamber 14 to the top may be added to the sidewalls 36a,36b, 36c, 36d to aid in the positioning of the stored slides when theslides reached the top of the chamber 14 as shown in FIGS. 1 and 5embossments 46 may be formed on any or all of the sidewalls.

A generally square cover 12, with grooves 42 along two parallel edgeswhich cooperate with the flanges 18 to permit relative slide movementbetween the cover 12 and the chamber 14, completes the magazine. A rim44, protruding substantially perpendicularly from the cover 12 along athird edge thereof, prevents removal of the cover 12 by abuttingsidewall 36a when the cover 12 is slid rightwardly into the closedposition.

As seen in FIG. 6, the groove 42 formed in the cover I2 is constrictedat 43, substantially adjacent the fourth edge of the cover 12. Forpurposes of clarity FIG. 6 has been depicted with the cover 12 rotatedfrom the position shown in FIG. 1. The constricted groove 43 will permitpassage of the associated flange 18 but not the irregularly shaped post8 because its height exceeds that of the flange 18. Thus the interactionof the constricted groove 43 and the irregularly shaped post 8 preventsremoval of the cover 12 by sliding in a leftwardly direction. It shouldbe noted that the configuration of the grooves 42 along both the edgesofthe cover I2 are substantially identical. The action of the posts 8,the rim 44 and the overlapping relationship of the grooves 42 with theflanges I8 prevent removal of the cover 12 from the storage chamber 14in normal use. Substantially captive, the cover 12 ordinarily will notbe misplaced, adding great convenience for the user.

The gap 19 between the flange l8 and the post 8 permits the cover 12,from the position in FIG. 1, to be rotated clockwise. In the positionshown in FIG. I, the post 8 is seated on surface 45 of the cover 12. Thegap 19, wide enough to accommodate the portion of the cover 12 lyingbetween surface 45 and the extreme rightward edge, allows passage of thecover 12 therethrough when the cover 12 is rotated clockwise about thepost 8. Such a rotation completely opens the storage chamber 14, therebyfacilitating removal of any slides stored therein.

Two indents 48 formed in the fourth edge of the cover correspond to thekeying projections 30 which nestle in the indents 48 when the cover isin closed relationship with the chamber 14. Keying cutouts 16 on thegrooved edges of the cover serve to ensure proper placement into theprojection apparatus. An embossed triangle 22 on the top of the cover I2aids in orienting the magazine 10.

To better understand the use of the magazine 10 reference is made toFIG. 2 wherein the magazine receiving portion of the slide projector isillustrated. A depression 26 in the projector housing 28 is shaped toaccommodate the magazine 10 with the cover 12 closed. An embossedtriangle 24 corresponding to the triangle 22 on the cover 12 aids inproperly aligning the magazine 10 for insertion. Two bosses 20 formed ontwo parallel edges of the depression 26 are similar in shape to thekeying cutouts 16 on the cover 12. When the cover 12 is properlyoriented in relation to the depression 26, the bosses 20 will nestleinto the keying cutouts I6 and permit the cover 12 to be placed into thedepression 26. FIG. 4 best illustrates the magazine 10 after initialinsertion into the depression 26.

Two grooves 38 are provided above the slide receiving station 50, morefully described in copending application Ser. No. 860,384, filed Sept.23, I969, to receive and surround the flanges l8, 18 when the storagechamber I4 is slid rightwardly into position over the receiving station50 as shown in FIG. 3. As shown therein, the slides 32 aregravitationally urged into the receiving station 50 and thence will betransported individually by a drive plate 34, also set forth in detailin copending application Ser. No. 860,384. Note in FIG. 5 that twocutouts 40 in edge 52 (FIGS. 2 and 3) accommodate the keying projections30.

After the slides 32 have been cycled through the projector a loadingplatform (not shown) is utilized in returning the slides to the storagechamber. That apparatus is set out in detail in copending applicationSer. No. 860,384. The keying projections 30 also serve to release theloading platform from detent means by wiping across its upper surfacewhen the storage chamber 14, now reloaded with slides, is slidleftwardly so that it may be removed from the projector housing 28. Theprojector may then receive a second magazine with different slidescontained therein.

Quite obviously, the compactness of the slide magazine, provides forconvenient storage and handling by the operator. The generally cubic orparallelpipedic shape permits easy stacking of several magazines andkeeps the packing factor near maximum.

Thus a novel slide container has been described that pro vides forconvenient storage of photographic slides and which is adapted forpositive insertion into and withdrawal from a slide projector.

it should be understood, of course, that the foregoing disclosurerelates to only a preferred embodiment of the invention and that manymodifications or alterations may be made therein without departing fromthe spirit and the scope of the invention as set forth in the appendedclaims.
